There's a compile-time option that you (or your distributor) can use
to change the default. However, if you take the original bash source
tarball and run "./configure" with no options and compile it, extglob
will be off by default.
hobbit:/usr/local/src/bash/bash$ ./configure --help | grep glob
--enable-extended-glob include ksh-style extended pattern matching
--enable-extended-glob-default
--enable-glob-asciiranges-default
hobbit:/usr/local/src/bash/bash$ ./configure --help | grep -A2 glob-default
--enable-extended-glob-default
force extended pattern matching to be enabled by
default
